If it's just money, a political science degree from Georgetown Universtiy had one of the highest average first year starting salaries for its graduates of any degree from anywhere, for several years. May still.
If money is the only ticker, any serious trade school can show you higher payoffs from one or two year ceritficates than almost any four year or more college degree. The income stream starts before the schooling is over, usually. My wife made 50k her first year out from a two year machinist program, while still an apprentice, with her schooling already paid for by night work obtained with the skills as acquired - contrast that with a 50k debt in the third year of an engineering degree from a good school, and a trade school breaks down to be 200k + advantage on day one. Hard to catch that.
Plumbing pays even better. Hydraulics.
An education degree is probably worthless in what it signifies. But a lack of schooling in education is a serious handicap for someone who wants to teach professionally - the world is full of technologically capable people who can't teach and don't know that. That's why you have to go to school to be an engineer - on the job you'd be taught by engineers, and experience has shown that to be not so productive.
Don't mistake low standards of performance for an easy job.
